Sorry if this has been posted already but I came accross a great website that helps you calculate costs to help you when planning a baby or when you have a baby. Theres loads of other advice and links to things like hmrev and direct gov to see if you qualify for certain allowances etc too but I just felt that this put my mind at ease as money was a bit of a concern for me. Im planning on ttc in July and was worried incase I was getting carried away and not really thinking of the costs, it may not help everyone but I found it handy so thought i would share :\)
